Abstract
To reduce the transmission requirement of transmitting data between brake controlled microprocessors (7, 8, 9; 20-25) and a reference microprocessor, or reference microprocessor section (15) within one of the wheel speed microprocessors, the microprocessors are connected in a ring connection, or ring bus (13; 26, 27). The microprocessors generate, in each processing cycle, a code number based on the then pertaining operating conditions of the wheel or axle with which the respective microprocessor is associated. A code number determines one of several slopes for changing the reference signal. The code numbers are applied to the ring connection and thus to the reference microprocessor, where they are compared with stored code numbers, in which the stored code numbers are arranged in a predetermined priority sequence. Dependant on this comparison, a new reference signal is then generated which is transmitted to the microprocessors over the ring connection or ring bus for use as a reference value in calculating possible positive or negative slip of an associated wheel or the wheels of an associated axle. The system is particularly simple to check since transmitted code numbers, being recirculated in the ring connection, can be compared with previously transmitted code numbers.
